Description

TECHNICAL FIELD

[0001] The present application relates to the technical field of aerosol generation, in particular to an atomizer with a child lock and an air adjusting mechanism and an aerosol generating device. BACKGROUND

[0002] An aerosol is a gaseous dispersion system composed of solid or liquid particles suspended in a gaseous medium. Existing aerosol generating devices generally have an atomizer. The atomizer is provided with an atomizing core. After the user starts the device, the heating element in the atomizing core converts electrical energy into heat energy to heat the aerosol substrate in the device, forming an aerosol for the user to consume. The aerosol substrate is a thermoreversible material, generally in a liquid, solid or gel state. Through heating, the aerosol substrate can be converted into an aerosol.

[0003] The existing atomizer generally has an electrode at the bottom. The combination of the atomizer and the main machine constitutes an aerosol generating device. In the present aerosol generating device, the electrode at the bottom of the atomizer is electrically connected with the conductive end on the main machine. When the user opens the switch on the main machine, the circuit in the main machine forms a loop with the electrode and the atomizing core in the atomizer, so that the atomizer can work and generate an aerosol. This kind of aerosol generating device is easy to work under the mistaken operation of children.

[0004] The air adjusting mechanism is a mechanism arranged on the atomizer to adjust the air intake of the atomizing core. The user can adjust the air adjusting mechanism according to the size of the required aerosol flow to meet the different use requirements of the user. Some existing inventors set an air passage on the electrode of the atomizer. By rotating the electrode, the related air passage of the atomizer can be controlled. When the electrode is rotated to disconnect the air passage, even if the child mistakenly operates the power switch of the atomizer, the atomizer cannot generate an aerosol, which can achieve a certain child lock effect.

[0043] The present invention will be further described below with reference to the accompanying drawings and embodiments.

[0044] This invention improves the structure of the atomizer, making it necessary to press and rotate the atomizer to connect the air passage on the atomizer electrode with the atomizer core, thereby better preventing the atomizer from generating aerosols due to accidental operation by children.

[0045] Figure 1 The external structure of an atomizer 100 according to one embodiment is schematically shown. Figure 2 The diagram illustrates its internal structure. Figure 3 right Figure 2 The middle section A has been enlarged.

[0046] This atomizer 100 includes a housing 110, within which an atomizing core 130 is disposed. The atomizing core 130 is used to heat and atomize the aerosol matrix. An electrode hole 111 is provided at the bottom of the housing 110. A first air outlet 112 is provided on the wall of the electrode hole 111. An electrode 120 is movably connected within the electrode hole 112. The electrode 120 has an air passage 122, which has an air inlet 121 and a second air outlet 123. An elastic member 180 is provided between the electrode 120 and the housing 110, providing a downward elastic force to the electrode 120. Figure 3 In this state, the second air outlet 123 is offset from the first air outlet 112, which disconnects the air passage 122 from the air inlet of the atomizing core.

[0047] exist Figure 3 In this state, electrode 120 cannot be rotated directly. Electrode 120 must be pressed upwards first before it can be rotated.

[0048] Figure 4 and Figure 5The diagram schematically illustrates the state of electrode 120 after it has been pressed upwards and then rotated. In this state, the second air outlet 123 is aligned with the first air outlet 112, thereby making the air passage 122 and the air inlet 134 of the atomizing core 130 in a conductive state.

[0049] like Figure 4 As shown, an embodiment of the atomizing core 130 includes an atomizing tube 133, a heating element 131, and a conductive part 135. The atomizing tube 133 is supported within the housing 110 by the bottom of the housing 110, forming a seal with the container 140 of the aerosol matrix. The atomizing tube 133 has a liquid inlet 132 and an air inlet 134. The liquid inlet 132 communicates with the container 140, and the air inlet 134 communicates with the air intake channel. The heating element 131 is fixed inside the atomizing tube 133 and corresponds to the position of the liquid inlet 132. The heating element 131 consists of a substrate and a heating circuit disposed on the substrate. The substrate can be metal, porous ceramic, etc., and the heating circuit can be attached to the substrate by sputtering, printing, embedding, or other methods. The conductive part 135 is formed by heating lines extending to the bottom of the housing 110 and is electrically connected to the electrode 120.

[0050] like Figure 4 As shown, in one embodiment, the top of the atomizing core 130 is connected to the mouthpiece 160 on the top of the housing via an air duct 150.

[0051] When electrode 120 is electrically connected to the conductive part on the main unit, the main unit supplies power to the heating element 131, which converts electrical energy into heat energy. The aerosol matrix in container 140 enters the atomizing tube 133 through the liquid inlet 132, where it is heated and vaporized by the heating element 131 into aerosol. At the same time, external gas enters the atomizing tube 133 through the air passage 122, the second air outlet 123, and the first air outlet 112 on electrode 120, and then through the air inlet 134. After mixing with the aerosol, it is output along the air guide tube 150 to the mouthpiece 160 for the user to inhale.

[0052] It should be noted that the above-described structure of the atomizing core 130 and the air outlet channel from the atomizing core to the mouthpiece are merely examples, and existing atomizing cores and air outlet channels in the field of atomizers can also be used. The atomizing core and air outlet channel in this invention are not limited to the specific structure described above.

[0053] exist Figure 5 In this state, first rotate electrode 120 in the opposite direction, then pull electrode 120 downwards to return. Figure 3 The state shown.

[0054] As can be seen, to establish airflow between the air passage 122 on the electrode 120 and the atomizing core 130, the atomizer 100 requires pressing the electrode 120 upwards and rotating the electrode 120. Children's operation is usually a simple, single action; therefore, the atomizer 100 can more reliably prevent aerosol generation due to accidental operation by children.

[0055] The aforementioned movement of electrode 120 can be achieved by guiding the structure between electrode 120 and electrode hole 111. Figure 6 to Figure 8 The schematic diagram illustrates the structure of an electrode 120 in one embodiment. Figure 9 to Figure 12 The schematic diagram illustrates the construction of an electrode hole 111 in one embodiment.

[0056] Reference Figure 7 and Figure 8 In this embodiment, in addition to the air passage 122, air inlet 121, and second air outlet 123 described above, the electrode 120 also has a first protrusion 124 on its side. (Refer to...) Figure 11 and Figure 12 In this embodiment, the electrode hole 111 has a first straight groove 1113 and a first rotating groove 1111 on its wall. The first rotating groove 1111 communicates with the top end of the first straight groove 1113. The first straight groove 1113 and the first rotating groove 1111 allow the first protrusion 124 to slide within them to control the movement path of the electrode 120.

[0057] Reference Figure 11 and Figure 12 The electrode hole 111 also has a second rotating groove 1112 on its wall. The second rotating groove 1112 communicates with the first straight groove 1113 and is away from the top of the first straight groove 1113. In this embodiment, when the electrode 120 is pulled down, it can be rotated so that the first protrusion 124 is inserted into the second rotating groove 1112. Therefore, to align the second vent 123 with the first vent 112, the electrode 120 needs to be rotated first, and after the first protrusion 124 disengages from the second rotating groove 1112, the electrode 120 needs to be pressed upwards, and then the electrode 120 needs to be rotated again. This requires two rotation steps and one pressing step, thus increasing the reliability in preventing accidental operation by children.

[0058] In the above embodiments, the first straight groove 1111 is configured to extend vertically, and the first rotating groove 1111 is configured to extend horizontally circumferentially. The present invention is not limited to this; as long as the air passage 122 and the atomizing core 130 are connected or disconnected by pressing or pulling the electrode 120 in the first direction and applying rotational force around the first direction, the air passage can be opened or closed. For example, as another embodiment, the first rotating groove 1111 can also be configured as a spiral. As yet another embodiment, such as...Figure 13 As shown, a second straight groove 1116 can also be provided on the wall of the electrode hole 111, so that the top end of the second straight groove 1116 is connected to the end of the second rotating groove 1112 away from the first straight groove 1113. In this way, two pressing or pulling steps and two rotation steps are required to align the second vent 123 with the first vent 112, which will further improve the reliability of preventing children from accidentally operating the device. The second straight groove 1116 can also be configured to extend upward from the left end of the second rotating groove 1112. As another embodiment, the second rotating groove 1112 can also be arranged parallel to the first rotating groove 1111. Understandably, the grooves and the first protrusion 124 can also be interchanged, that is, the first protrusion 124 is provided on the wall of the electrode hole, and the grooves that cooperate with the first protrusion 124 are provided on the side of the electrode 120.

[0059] Reference Figure 9 and Figure 10 In one embodiment, the first rotating groove 1111 is provided with a plurality of second protrusions 1115. The second protrusions 1115 are used to cooperate with the first protrusion 124 to position the electrode 120. Different second protrusions 1115 correspond to different air intake volumes. When the first protrusion 124 abuts against different second protrusions 1115, the alignment degree of the second air outlet 123 and the first air outlet 112 is different, or the degree of overlap is different. Therefore, the air intake volume of the atomizing core 130 is different.

[0060] Reference Figure 8 In one embodiment, the electrode 120 is provided with a plurality of second air outlets 123, which are arranged circumferentially at intervals on the sidewall of the air passage 122. When the first protrusion 124 engages with different second protrusions 1115, different numbers of second air outlets 123 align with the first air outlet 112. As another embodiment, the number of first air outlets and the number of second air outlets can both be one, utilizing the principle that the overlap of the two air outlets changes when the electrode 120 rotates to achieve adjustment of the air intake volume.

[0061] Refer again Figure 9 and Figure 10 The first rotating slide 1111 also has a third protrusion 1114, which engages with the first protrusion 124 and prevents the electrode 120 from rotating. The height of the third protrusion 1114 is greater than the height of the second protrusion 1115. By engaging the third protrusion 1114 with the first protrusion 124, the electrode 120 can be locked at the current air intake position. It is understood that a third protrusion can also be provided in the second rotating slide to engage with the first protrusion to lock the position of the electrode 120.

[0062] Further reference Figure 4 andFigure 5 In this state, the air passage 122 on the electrode 120 is connected to the air inlet 134 of the atomizing core 130. Furthermore, the electrode 120 is also in contact with the conductive part 135 of the atomizing core 130. That is, when the electrode 120 is in this state, both the air passage and the circuit of the atomizing core 130 are connected. Figure 2 and Figure 3 In this state, the air passage 122 on the electrode 120 is disconnected from the air inlet 134 of the atomizing core 130. Furthermore, the conductive portion 135 of the electrode 120 and the atomizing core 130 is also disconnected. Therefore, by pressing or pulling the electrode 120 in a first direction, and by applying rotational force around the electrode 120 in that first direction, the atomizer 100 can not only connect or disconnect the air passage 122 and the atomizing core 130, but also connect or disconnect the electrical circuit between the electrode 120 and the atomizing core 130. Thus, the reliability of preventing aerosol generation in the atomizer due to accidental operation by children can be further improved.

[0063] Further reference Figure 4 and Figure 5 In one embodiment, the first air outlet 112 is offset vertically from the air inlet 134 on the atomizing core 130, resulting in a longitudinal air passage 1341 formed on the outer side of the atomizing core 130. The first air outlet 112 communicates with the air inlet 134 of the atomizing core through this longitudinal air passage 1341. This increases the contact area between the air inlet channel and the atomizing tube 133. During heating, this increases the contact area and contact time between the air and the atomizing tube 133, which is beneficial for cooling down the atomizing core 130.

[0064] Reference Figure 14In one embodiment, the housing 110 includes a body 113 and a bottom 116 attached to the lower end of the body 113. Together, they form a matrix container 140, which stores a thermally reversible aerosol matrix that can be converted into an aerosol after being heated by the atomizing core 130. The bottom 116 also serves to fix the atomizing core 130 and the electrode 120. In one embodiment, the bottom 116 of the housing consists of an outer base 115 and an inner base 114. The atomizing core 130 and the electrode 120 are fixed to the outer base 115, which is made of a rigid material, such as hard plastic, to ensure reliable support for the atomizing core and the electrode. The inner base 114 is made of an elastic material, such as silicone or rubber. The inner base 114 is sealed to the inner wall of the body 113 and the outer wall of the atomizing core 130, giving the container 140 good sealing properties. As another implementation, the inner seat 114 and the outer seat 115 can also be an integral structure made of the same material, as long as the selected material has appropriate rigidity and elasticity to ensure reliable support for the atomizing core 130 and the electrode 120, and to ensure good sealing of the container 140. The inner seat 114 is made of an elastic material, which also serves to realize the second vent 123 (see...) when the child lock is engaged. Figure 3 ) seal, combination Figure 2 , Figure 3 and Figure 11 Specifically, the first air outlet 112 is formed in the inner seat 114, and a seal is formed between the side wall of the electrode 120 and the inner seat 114. When the second air outlet 123 is offset from the first air outlet 112, the second air outlet 123 is sealed by the inner seat 114. In this way, when the air passage 122 is disconnected from the atomizing core in the air path, the air pressure inside the atomizer is lower than the ambient air pressure, which can achieve a leak-proof effect. It should be understood that this shell structure is only a specific example of the present invention, and the shell of the atomizer in the present invention is not limited to this.

[0065] Refer again Figure 8 The bottom circumferential surface of electrode 120 is provided with an embossed structure 125, which facilitates manual rotation of the electrode to adjust the air intake.

[0066] As can be seen from the above, the improvements to the atomizer structure require pressing and rotating steps to connect the air passage on the electrode to the atomizer core. This operation is usually unknown to children, thus better preventing aerosol generation due to accidental child operation. In some embodiments, both the air passage and the electrical circuit are disconnected, resulting in even higher reliability.

[0067] In the following embodiments, by operating electrode 120, the atomizing core can be switched between on and off states in terms of circuit, gas path, and liquid path. Any content not described in the following embodiments is the same as in the foregoing embodiments.

[0068] Figure 15 The structure of the electrode 120 used therein is shown. This electrode 120 includes an air passage 122, which has an air inlet 121 and a second air outlet 123, the structure of which is the same as in the aforementioned embodiment. Furthermore, the top of the electrode 120 is provided with a downward-facing slot 126, and the wall of the slot 126 is provided with a second liquid hole 125.

[0069] Figure 16 to Figure 19 An embodiment of an atomizer is shown, wherein, Figure 16 This is a state where the electrical circuit, gas circuit, and liquid circuit are all disconnected. Figure 17 for Figure 16 A magnified view of a portion of the image. Figure 18 This indicates that the electrical circuit, gas circuit, and liquid circuit are all conductive. Figure 19 for Figure 18 A magnified view of a portion of the image.

[0070] This embodiment of the atomizer includes a housing 110, an electrode 120, and an atomizing core 130. The housing 110 includes a shell body and a bottom attached to the lower end of the shell body, which together form a matrix container 140. The bottom of the housing 110 is composed of an outer seat and an inner seat, and the implementation method is basically the same as the previous embodiment. The difference is that a first liquid hole 1321 is provided on the wall of the electrode hole 111 of the inner seat 114, more specifically, at a position opposite to the liquid inlet hole 132 of the atomizing core 130. The first liquid hole 1321 communicates with the liquid inlet hole 132 of the atomizing core. The slot 126 on the electrode 120 communicates with the matrix container 140. The liquid inlet channel of the atomizing core is formed from the matrix container 140, the slot 126 on the electrode 120, the second liquid hole 125 on the electrode, the first liquid hole 1321 on the wall of the electrode hole 111, to the liquid inlet hole 132 of the atomizing core.

[0071] Figure 16 and Figure 17 In the indicated state, on one hand, the second air outlet 123 on the electrode 120 is misaligned with the first air outlet 112 on the wall of the electrode hole 111, disconnecting the air passage 122 on the electrode 120 from the atomizing core in the air path; on the other hand, the electrode 120 is detached from the conductive part 135, disconnecting the electrode 120 from the atomizing core in the circuit; and thirdly, the second liquid hole 125 is misaligned with the first liquid hole 1321, disconnecting the slot 126 on the electrode 120 from the atomizing core in the liquid path. Because the atomizer is disconnected from the air path, the circuit, and the liquid path, this embodiment provides higher reliability in preventing accidental aerosol output from children.

[0072] Reference Figure 17A first liquid hole 1321 and a first vent hole 112 are formed in the inner seat 114, and a seal is formed between the sidewall of the electrode 120 and the inner seat 114. Since the inner seat 114 is made of an elastic material, thus, Figure 17 In the indicated state, the first liquid hole 1321 and the first vent hole 112 are sealed by the inner seat 114, and the internal air pressure of the matrix container is lower than the ambient air pressure, which can play a role in preventing leakage.

[0073] exist Figure 16 and Figure 17 In this state, first press electrode 120, then rotate electrode 120 to enter. Figure 18 and Figure 19 Status. (Refer to) Figure 19 In this state, the second air outlet 123 on the electrode 120 is aligned with the first air outlet 112 on the electrode hole wall, so that the air passage 122 on the electrode 120 is connected to the air inlet 134 of the atomizing core; the electrode 120 is in contact with the conductive part 135 and is conductive; the second liquid hole 125 is aligned with the first liquid hole 1321, so that the slot 126 on the electrode 120 is connected to the atomizing core in the liquid path. In one embodiment, by rotating the electrode 120, the overlap between the second liquid hole 125 and the first liquid hole 1321 can be adjusted, and the overlap between the second air outlet 123 and the first air outlet 112 can be adjusted simultaneously, thereby realizing the synchronous adjustment of the air intake and liquid intake of the atomizing core. It can be understood that by designing the position and aperture of the second liquid hole 125 and the second air outlet 123, the adjustment ratio of the liquid intake and air intake can be made equal or unequal.

[0074] The structure for adjusting the liquid intake is the same as that for adjusting the air intake, and will not be described further here.

[0075] This embodiment, through operation of the electrode 120 of the atomizer 100, can achieve switching control of the atomizing core 130 from three aspects: circuit, air path, and liquid path, as well as synchronous adjustment of the liquid inlet and air inlet. Therefore, it is safer and easier to operate.

[0076] Combining the aforementioned atomizer with the main unit of the aerosol generating device constitutes the aerosol generating device. After combination, the atomizer's electrodes are electrically connected to the conductive parts of the circuitry on the main unit, forming a circuit between the main unit's circuitry, the atomizer's electrodes, and the atomizer's heating circuit. This allows the atomizer to operate, heating its internal aerosol matrix to convert it into aerosol, which is then mixed with air entering through the air intake channel and output for the user to inhale. When not in use, the atomizer is removed. First, the electrodes are rotated, then pulled out, disconnecting the atomizer from the circuitry, airflow, and liquid flow; or from the circuitry and airflow, or only from the airflow. Then, the atomizer is reassembled with the main unit. This prevents the atomizer from activating even if a child accidentally touches the aerosol generating device's switch. Furthermore, even if a child disassembles the main unit and atomizer and rotates or presses the electrodes, the air holes on the electrodes cannot be connected to the atomizer coil in the airflow path, thus preventing the atomizer from outputting aerosol. Therefore, this method effectively prevents aerosol output due to accidental child operation.

[0077] Unless otherwise specified, the terms "first," "second," and similar terms mentioned above are used to distinguish different devices with the same name and should not be interpreted as implying order, hierarchy, or degree of importance.
